John Woody Papworth (4 March 1820 – 6 July 1870) was an English architect, designer and antiquary. He is chiefly remembered for "Papworth's Ordinary" (1874), a reference guide to British and Irish coats of arms arranged systematically according to their design. G. D. Squibb commented in 1961 that "his memory rests more securely upon his Ordinary of British Armorials than upon any building for which he was responsible, though it is but fair to add that his professional achievements were not lightly regarded by his contemporaries".
